Pneumatic Electric Nail Gun Buffer Mount for Recoil Shock Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pneumatic electric nail guns suffer from damage to the reduction gear set due to recoil shock, which is not adequately mitigated by existing torque dispersion mechanisms.
Innovation Solution
The pneumatic electric nail gun incorporates a connecting unit with fasteners and buffer members made of flexible materials like silicon rubber, plastic, or silica gel, which absorb shock and allow the casing to move slightly, thereby dissipating recoil forces and protecting the gear set.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the reduction gear set is rotated by a motor to drive the lifting wheel and striking member, then the nail-striking process is initiated, but the recoil shock transmitted throughout the speed reduction unit causes damage to the reduction gear set
Solution Approach 1:
The patent introduces a cushioning member made of elastic material positioned between the connecting portion and the casing. This cushioning member is installed beforehand to absorb and mitigate the recoil shock before it reaches the reduction gear set, preventing damage while maintaining the motor's driving power for initiating the nail-striking process
Solution Approach 2:
The cushioning member acts as an intermediary element between the rigid connecting portion and casing. It mediates the transmission of recoil shock by deforming elastically, thereby protecting the reduction gear set from direct impact while still allowing the motor to effectively drive the lifting wheel and striking member
2Strength
If the first and second coupling segments are arranged around the second axis to disperse torque, then stress concentration and damage to the surrounding portion and connecting portion are avoided, but the recoil shock can still damage the reduction gear set
Solution Approach 1:
The cushioning member is installed beforehand between the connecting portion and casing to provide shock absorption. While the coupling segments disperse torque to prevent structural damage, the cushioning member specifically protects the reduction gear set from recoil shock that passes through the speed reduction unit
Solution Approach 2:
The patent applies different functional qualities to different parts: the coupling segments provide torque dispersion for structural strength, while the locally installed cushioning member provides shock absorption for reliability. This local differentiation allows each component to optimize its specific function without compromising the other

AI summary
A pneumatic electric nail gun includes a muzzle unit, a striking cylinder that is connected to the muzzle unit, a piston rod subunit that extends movably from the striking cylinder into the muzzle unit, an electric unit that drives movement of the piston rod subunit from a standby position to a nail-striking position for striking a nail, and a connecting unit that includes a plurality of fasteners and a plurality of buffer members. The fasteners extend through the electric unit and secure the electric unit to the muzzle unit. Each of the buffer members surrounds a respective one of the fasteners and fills a space between the respective one of the fasteners, the electric unit and the muzzle unit for shock absorption during a nail-striking process.
